The owners of a San Diego home-appraisal company that shut down last year have been fined $855,000 for failing to pay Arizona appraisers 171 times, in a decision reached by an Arizona public agency on Friday.

Members of Arizona’s board of appraisal unanimously approved fining AppraiserLoft and revoking its license to operate as an appraisal management company in that state. Since the mortgage bubble burst, such companies have been used increasingly to block collusion between banks and appraisers.

The recommendations to fine the firm and revoke its license came from an administrative law judge, who heard the case in June.

Neither company founder Aman Makkar nor his wife, Harpreet Makkar, majority owner of the company, appeared at Friday’s hearing in Phoenix.

The Attorney General’s Office will pursue the fine, but it’s unclear what the consequences would be if the money is not paid. The Attorney General’s Office could not immediately be reached for comment.

AppraiserLoft has been at the center of several non-payment and late-payment claims from appraisers, former employees and other parties, before and after it shuttered suddenly in October, according to public records.

Company officials, who said they had more than 20,000 appraisers in their network, have been accused by dozens of appraisers across the country of paying several months late or not paying at all. They also allege they were never notified of the company’s closure.
